libmemcached: libmemcached-awesome is an open source C/C++ client library and tools for the memcached server
CVE-2023-27478 is fixed in libmemcached on 1 platform, first by DEBIAN-CVE-2023-27478, released March 7, 2023. It is not reported as exploited. Patch Radar priority: Routine.
libmemcached-awesome is an open source C/C++ client library and tools for the memcached server. `libmemcached` could return data for a previously requested key, if that previous request timed out due to a low `POLL_TIMEOUT`. This issue has been addressed in version 1.1.4. Users are advised to upgrade. There are several ways to workaround or lower the probability of this bug affecting a given deployment. 1: use a reasonably high `POLL_TIMEOUT` setting, like the default. 2: use separate libmemcached connections for unrelated data. 3: do not re-use libmemcached connections in an unknown state.
